Clouds form through the condensation of water vapor, an action which is duplicated by this apparatus. A glass bulb with a wide tube, 500 ml capacity, is attached to a large rubber bulb at one end. A clamped rubber tube is attached to an opening on one side of the tube. You fill the 9cm-diameter rubber bulb with water, squeeze it slightly and then release it suddenly. A dense cloud is released from the rubber bulb. You can show the effects of dust particles and ionized air on the newly formed cloud as well. With instructions.
